Please, I don't have a crystal ball. Post the link and a picture and I'll try to help further.
Do you mean this ??????????????????????????
I would ask you why you have posted, since you seem certain that you know best.
As I have already mentioned, you should NOT feed 2 loads from 1 fspur, so it's academic as to the Crabtree unit in
screwfix (which does NOT appear to be the switched variety mentioned in the
Screwfix descriptive with in line fuse). You need to provide a 3a fspur to feed the cable to it's end point where the shaver socket is required.
You MUST provide equipotential bonding (or run the risk of electrocution) and you SHOULD not be doing bathroom (wet are) electrics without being aware of the regs and the fact that as an unqualified person you should not be doing the work.
Hint, certificates and test results
Look on the DIYNot Wiki and read up on bathrooms, zones and regs.
I've got the hump now, have you an understanding of the words 'please' or 'thanks'.
